Problems solved by technology

[0002] At present, domestic cement bricks mainly use fly ash, coal slag, coal gangue, tailings slag, chemical slag or natural sand, sea mud, etc. as the main raw materials, and use cement as a coagulant without high-temperature calcination. A new type of wall material , in line with the development trend of building materials in my country "protecting farmland, saving energy, adapting measures to local conditions, and using local materials", but the disadvantage of this type of material is that it is not as good as red brick when combined with plastering mortar, and it is easy to produce cracks on the wall, which affects the use; and this cement brick The function is single, and the effects of fire prevention, heat preservation, and sound insulation are not good enough, and it cannot meet the country's requirements for reducing energy consumption and improving energy-saving effects of building materials. Therefore, the application of the present invention is of great significance

Embodiment 1

[0030] Such as figure 1 , figure 2 As shown, taking the quadrilateral cement board as an example, its content is: the weight percentage of each component is Portland cement 5%, anhydrous chloride 12%, magnesium oxide 30%, magnesium sulfate 7%, anhydrous gypsum powder 8% , fly ash 25%, rice husk 10%, and the rest are additives; additives are phosphoric acid, gelatin, three sodium, polypropylene fiber.

[0031] The surface of the cement board is fully enclosed, including an insulation layer 3, a sound insulation layer 4 and an enclosure support frame 2; the enclosure support frame 2 is formed at one time, including a top layer 21, a bottom layer 22, a peripheral frame 23 and a support column 24, The support column 24 is perpendicular to the top layer 21 and the bottom layer 22 and connected with them, so as to stabilize the frame structure of the cement board, not easy to deform, and improve the compressive strength of the cement board. The side length of the cement board is ...

Embodiment 2

[0040] A cement board, the content of which is: Portland cement 8%, anhydrous magnesium chloride 10%, magnesium oxide 25%, magnesium sulfate 11%, anhydrous gypsum powder 5%, fly ash 30% in weight percentage of each component , 12% of rice husk, and the rest are additives; said additives include phosphoric acid, gelatin, three sodium, polypropylene fibers.

[0041] The surface of the cement board is fully enclosed, including an insulation layer 3, a sound insulation layer 4 and an enclosure support frame 2; the enclosure support frame 2 is formed at one time, including a top layer 21, a bottom layer 22, a peripheral frame 23 and a support column 24, The support column 24 is perpendicular to the top layer 21 and the bottom layer 22 and connected with them, so as to stabilize the frame structure of the cement board, not easy to deform, and improve the compressive strength of the cement board. The side length of the cement board is 600mm×1200mm, and the thickness is 60mm. The ins...

Embodiment 3

[0050] A cement board, wherein the components: Portland cement 6%, anhydrous magnesium chloride 11%, magnesium oxide 28%, magnesium sulfate 9%, anhydrous gypsum powder 6%, fly ash 29%, rice 11% of the shell, and the rest are additives; the additives include phosphoric acid, gelatin, three sodium, polypropylene fibers.

[0051] The surface of the cement board is fully enclosed, including the insulation layer 3, the sound insulation layer 4 and the enclosure support frame 2; the enclosure support frame 2 is formed at one time, including the top layer 21, the bottom layer 22, the peripheral frame 23 and the support column 24. The support column 24 is perpendicular to the top layer 21 and the bottom layer 22 and connected with them, so as to stabilize the frame structure of the cement board, not easy to deform, and improve the compressive strength of the cement board. The side length of the cement board is 400mm×1000mm, and the thickness is 40mm. The insulation layer is composed ...

Abstract

The invention provides a fireproof, heat-preserving and sound-insulating cement plate. The surface of the cement plate is totally closed. The cement plate comprises a heat-preserving layer, a sound-insulating layer and an enclosure supporting frame, wherein the enclosure supporting frame is formed in one step and comprises a top layer, a bottom layer, a circumferential frame and a supporting pillar; and the supporting pillar is vertical to the top layer and the bottom layer and is connected with the top layer and the bottom layer. The plates are adhered to one another in a viscose mode and then are polished flatly. A manufacturing method of the plate is simple and convenient; the size of the plate is adjusted flexibly; suitable plates can be produced by selecting different sizes of dies according to the requirements of buildings; indoor space can be effectively saved; the using area of a room is increased; and the plate is energy-saving, low-carbon and environment-friendly.
